I received a few days ago my new scope: a hantek dso1122s.
Yesterday decided to try the bandwidth hack, with my surprise, I found that hantek had 'already hacked my scope' ( the scope already had the file /dst1202b in it and the 2ns timebase is already available ).
Sadly the only thing I can do is change the 'name' of the scope ( i think I should have to change logotype anf logotype.dis )... but I'm too lazy for that.
In conclusion I'm not happy for what hantek did to my scope... ;-)
P.P.S. my unit was advertised as having 2M memory, but it has only 1M
It was a used unit, I wasn't expecting the latest version,
I got it for about half the price compared to how much a new unit costs (at least for my area), so I thought to give it a try.
Do you believe the version I got (hw0) is vastly inferior (regarding signal accuracy / performance etc.) to the latest version (hw1007) Hantek DSO5102B?
However this looks to me like an older firmware version (so probably not worth it). I assume the number "120423" is a date code and means April 23rd 2012, is that correct?
If I ever need a different firmware version, (I doubt it, your firmware 130814.1 works great, but I wanted to ask anyway) should I assume that Tekway firmwares (for the DST1102B) should work on my Hantek DSO5102B? Tekway's firmware filename is "dst1kb_2.06.3_01102b_fe(120423.0).up".
Here a few, not so good, photos of one side of the hantek dso1122s board:
P.S. by the way I'm looking for the sd socket, have you got a suitable part number ( or farnel/mouser code )

btw, something completty offtopic - did anyone recognized that Hantek have now new AWGs? e.g. HDG2002B, this is the cheapest model, but for me it looks like the DAC is running anyway same speed on all models, so maybe time to hack it ?
I don't have spare money to give a try, so hope someone will soon buy one and play a bit with them

I received mine last week. If someone is intereded I could post some photos of the board.
The software hack for unlocking frequencies is very simple. You just have to change the model name in the system.inf (now in /etc) and reboot...
So I just replaced HDG2002B with HDG2102B to get 100Mhz instead of 5Mhz.
At the moment I don't know if there is also some hardware mod to do (a 100Mhz sine of 2V amp is shown with 300mV amp on my MSO5062D with PP-200 Hantek probe, but I didn't mod the frontend yet)
Still have some some work in progress on my MSO ;-)
holy shit! please make a new topic on that, this is really awesome!size]
Sounds sad but it would even match the scope i just ordered..

I know what you are talking about...I bought it to match my MSO5062D
I'm interested in the MSO5074FG ... mainly for budget reasons. ($700 max )
I have read page 1, and now page 151 ( hence the edit ).
So, I can change a file name in root and get the 200MHz bandwidth ( after doing a backup which IS available in the software on SN 15000 upwards )
Near ADCs (that two ICs on top and two on bottom, each of them with small heatsink) on top and bottom there are on each side two ICs, on one of the pictures i think i can read NXP and HEF4053. If that's the case, one have to replace them by e.g TI CD74HC4053 to get more bandwidth, these NXP ICs they only good to 70MHz.
From your pictures i can tell you alrady that the acually used the new "B" model platform, added two extra channels, added necessary logic for triggering, repalced the two channel-mux relais with 4pcs of i think HEF4053 (which is for 70MHz bw ok), added an small DDS PCB and that's all. Where the LA is connected, no idea (as said above, can't see from the pictures).
So for sure it will not do 2GS/s but 1x1GS/s, 2x500MS/s and 3/4 x 250MS/s, so like Rigol DS1000Z. Why they not used the same ADC as Rigol is using, no idea, from price point of view should be same. The good think is, it looks like they changed the way the FPGA is clocking, they added two mif files for the PLL, they can be externally loaded, so it looks for me that they trid to improve the ADC clocking, which is good think. Anyway, we wil see (well, you) how that baby performs.
I downloaded the manual prior to finalizing a purchase decision and there is no obvious mention of a trigger output that I could use to trigger my USB logic analyzer. Does anyone have info on that please ?
I know that this may be off topic, but I'm looking for a hackable MSO/DSO with Logic Analyzer that has good memory depth and that can trigger on SPI, I2C etc, and either, have a trigger output to trigger my USB logic analyzer ( which does have protocol analysis), or, output signals to a PC so that software protocol decoding can be done there. I know the RIGOL DSO will trigger on I2C and SPI, but won't decode. Given the level of activity and knowledge on the Hantek scopes I assumed that someone must have the same desires as me.
Also, this scope is now $464 plus $80 shipping to USA... approx $80 cheaper than amazon, or USA dealers.
The latest firmware on the Hantek site contains dso5kb_func_dso5102b20140111.up. Can you more knowledgeable people tell me if this is the same as what i have, or is it an update from what I have installed?? (see picture in my last post). From the numbers it looks like an update but will it be suitable for my revision 1010 machine??. I Think I read somewhere further back, that someone bricked there scope with a update that was unsuitable. Last thing i want to do is screw up my scope!!
